Answer:
Smaller
Explanation:
Net force = Total mass * acceleration
If there is no friction, the net force is the tension in the second rope. Let’s assume the mass of each block is 2 kg, and the tension in the second rope is 8 N.
8 = 4 * a
a = 2 m/s^2
Since there is friction, the tension in the first rope is causing the first block to accelerate. To determine tension, use the following equation.
F = m * a
T = 2 * 2 = 4 N
If there is no friction and both blocks have the same mass, the tension in the second rope will be less than the tension in the first rope. I hope this helps you. If the masses are different, you can use this method to determine the tension in the first rope.
Answer:
primary succession is something that was t there before like a forest it once wasn’t there

Answer:
Your answer would be D. be pushed down into their seats.
Explanation:
You can think of it this way:
If you're not wearing a seat belt on an airplane that drops suddenly, in this case, vertically, which often happens with turbulence- you're the one at rest. You'll stay at rest as the plane (literally) drops out from under you.
If you're strapped in, the seat belt serves as an outside force acting on you, taking you with the plane as it drops and saving you from hitting the ceiling.
Always remember Newton's first law of motion: A body at rest will remain at rest unless an outside force acts on it.
